Question

Provide the correct structure for your unknown based on the spectroscopic data provided. Provide the correct name for your compound. Either the IUPAC name, or a commonly accepted name (i.e., ethyl acetate in place of ethyl ethanoate) will be accepted.IR spectrum: Assign as many peaks as possible. In particular, you should assign peaks that were important in making your structural interpretation (i.e. functional group peaks such as OH, C=O, N-H, etc.).

1H-NMR spectrum: Assign all the peaks in the spectrum to the appropriate hydrogen or group of hydrogens. Draw the unknown structure on the NMR spectrum and label each set of inequivalent protons. Use these labels in assigning the peaks.
13C-NMR spectrum: Assign all the peaks to the appropriate carbon or groups of carbons. Draw the unknown structure on the NMR spectrum and label each set of non-equivalent carbons. Use these labels in assigning the peaks.

Briefly discuss important features of the IR, 1H NMR, and 13C NMR that led you to the structure you propose.
